Figure Legend Snippet: SMARCA4 loss results in cancer cell–intrinsic defects in expression of innate immune and inflammatory genes. A and B, Immunoblots of parental and SMARCA4 KO H2122 ( A ) and HCC44 ( B ) cell lysates stained using anti-SMARCA4 and β-actin antibodies. C and D, Expression of STING1 , IL1β , and IFNβ mRNA levels was evaluated in parental and SMARCA4 KO H2122 ( C ) and HCC44 ( D ) cells treated with control and 10 μg/mL 2′3′-cGAMP for 6 hours ( n = 3 biological replicates) by qRT-PCR. E and F, STING1 , IL1β , IFNβ , and IRF3-P mRNA expression levels were evaluated in parental and SMARCA4 KO H2122 ( E ) and HCC44 ( F ) cells treated with control and 5 μg/mL poly (dA:dT) overnight ( n = 3 biological replicates) by qRT-PCR. G, HCC44 IL1β secretion was evaluated by ELISA. H, Immunoblot analysis of STING1, IL1β, IFNβ, IRF3, and IRF3-P in parental and SMARCA4 KO H2122 cells treated with control and 5 μg/mL poly (dA:dT) for 6 or 18 hours. I, Immunoblot showing inducible expression of SMARCA4 in SMARCA4 -deficient human lung cancer cell line H322 by administration of doxycycline (DOX; 1 μg/mL) with GFP as control. J, mRNA expression of STING1 , IL1β , and IFNβ by qRT-PCR in H322 control and SMARCA4 reconstituted cell line treated with control and 5 μg/mL poly (dA:dT) overnight ( n = 3 biological replicates). Data points represent the mean ± SEM. *, P < 0.05; **, P < 0.01; ***, P < 0.001; ****, P < 0.0001; ns, not significant, two-sided unpaired t test. CON, control; Par, parental.
Techniques Used: Expressing, Western Blot, Staining, Control, Quantitative RT-PCR, Enzyme-linked Immunosorbent Assay
Figure Legend Snippet: SMARCA4 degradation abrogates cancer cell–intrinsic expression of innate immune and inflammatory genes. A, SMARCA4 WT cells (HCC44, H1792, and H1975) and SMARCA4 mutation cells (H322, H1693, and H1299) were treated with DMSO control or 1 μmol/L ACBI1 for 96 hours. Immunoblots of SMARCA4 and β-actin in SMARCA4 WT cells (left) and SMARCA4 mutation cells (right). B–D, RNA-seq analysis of SMARCA4 WT (HCC44, H1792, and H1975) cells treated with DMSO vs. 1 μmol/L ACBI1 for 96 hours. B, GSEA curves showing upregulation of the inflammatory response and TNFα_signaling_via_NF-κB pathway in DMSO treatment. NES, normalized enrichment score. C, GSEA of hallmark top enriched pathways in DMSO treatment. Inflammatory response and IFNα response are at the top positions. D, Heatmap presenting the top 50 upregulated and downregulated genes in DMSO treatment, with IL1β being the one of significantly upregulated genes. E, qRT-PCR analysis of IL1β expression from SMARCA4 WT cells (HCC44, H1792, and H1975) treated with DMSO vs. 1 μmol/L ACBI1 for 96 hours and SMARCA4 WT cells (HCC44, H1792, and H1975) vs. SMARCA4 mutation cells (H322, H1693, and H1299). F, STING1 mRNA expression from SMARCA4 WT cells (HCC44, H1792, and H1975) treated with DMSO vs. 1 μmol/L ACBI1 for 96 hours. G, Immunoblots of STING1 and VINCULIN in H1792 cells treated with 0.1 or 1 μmol/L ACBI1 for 96 hours. Data points represent the mean ± SEM. *, P < 0.05; **, P < 0.01; ***, P < 0.001; ****, P < 0.0001, two-sided unpaired t test. MUT, mutant.

Figure Legend Snippet: Loss of SMARCA4 abrogates chromatin accessibility at enhancers associated with innate immune inflammation and are co-occupied by NF-κB. SMARCA4 WT cells (HCC44 and H1792) were treated with DMSO control or 1 μmol/L ACBI1 for 96 hours. A, Venn diagrams illustrating alterations in chromatin accessibility upon ACBI1 treatment along with annotation of ATAC peaks distribution across the genomic regions. B, ATAC-seq read density heatmaps for total peaks with DMSO and ACBI1 treatment in HCC44 and H1975. C, ATAC-seq read density heatmaps for enhancer peaks with DMSO and ACBI1 treatment in HCC44 and H1975. D, Pathway enrichment analysis for lost peaks in HCC44 and H1975 with ACBI1 treatment. E, Examination of transcription factor motifs on enhancers with lost accessibility with ACBI1 treatment as identified in D . F, Genome browser tracks of chromatin accessibility at IFNβ loci ( n = 2 biological replicates) in H1975 cells, following with representative integrative genome viewer tracks of views of the SMARCA4 and NF-κB CUT&RUN peaks on the IFNβ genomic locus. H3K27ac peaks derived from ChIP-seq denote putative enhancers. The overlapping peaks with differential intensity in the ACBI1 treatment group are highlighted. G, Endogenous interactions of SMARCA4 and NF-κB were analyzed by coimmunoprecipitation.
Techniques Used: Control, Derivative Assay, ChIP-sequencing
